- W2893587695 abstract "ABSTRACT Polymers containing CO 2 ‐philic groups are of great interest for CO 2 /light gas separation membranes because the affinity toward CO 2 can effectively increase CO 2 solubility and thus permeability. In this study, polysulfones (PSUs) modified with different degrees of benzyldimethylamine (DMA), benzyltrimethylammonium fluoride (TMAF), and benzyltrimethylammonium iodide (TMAI) were synthesized using sequential post‐functionalization reactions and investigated for CO 2 /N 2 and CO 2 /CH 4 separation. The physical properties of these polymers were studied, including density, fractional free volume, and glass transition temperature. In contrast to the conventional wisdom that tertiary amines exhibit an affinity toward CO 2 , this study convincingly shows that the DMA substituent has a minimal impact on CO 2 solubility and CO 2 /light gas solubility selectivity in PSUs under dry condition. On the other hand, incorporating TMAF and TMAI in PSU significantly increases CO 2 solubility. Particularly, introducing TMAI with a molar ratio of 1.07 relative to PSU repeating units increases CO 2 /CH 4 solubility from 4.4 to 5.2, CO 2 /CH 4 permeability selectivity from 21 to 45, and CO 2 /N 2 permeability selectivity from 24 to 33 at 35 °C, while the CO 2 permeability decreases from 5.6 to 1.7 Barrers. The effect of these functional groups in PSUs on gas diffusivity and diffusivity selectivity can be satisfactorily described by the free volume model. © 2018 Wiley Periodicals, Inc. J. Polym.
